DOORS & COMMERCIAL ENTR ANCE S
most excited about, and which has generated
immediate interest from fabricators, is the
entrance door. That’s because it gives us a very
comprehensive systems offer – and something
which our competitors don’t necessarily have –
plus incredible performance, particularly under
“It genuinely re-writes the rulebook about how
you specify aluminium entrance doors.”
DECALU ENTRANCE DOOR
The Decalu88 residential door delivers a
number of USPs. With a wide choice of flush
and glazed-in door slabs, consumer appeal is
one. Contemporary sightlines and sophisticated
styling give it reach in a wide variety of
Its true USP is, however, a maximum bowing
tolerance of only 2.5mm under heat stress.
Deceuninck Aluminium uses a pre-rolled highperformance
polyamide thermal-breaking system
throughout its range, including the Decalu88
Where it differs from the rest of the range is
that in Decalu88, it also features special ABS
inserts which adapt to temperature change
allowing the internal and external faces to
expand and contract independently of one
another, limiting bowing to a maximum of 2.5mm
– even in extreme heat.
This includes testing to 80°C or 176° F. “To
put that into context that’s double the highest
day time temperatures of most of the world’s
desserts. Optimistically, here in the UK even on
out hottest days, it’s nowhere close,” says Nigel.
The system also ‘works in reverse’, so that
even on the coldest day, deflection in the door is
limited to no more than 3.5mm at temperatures
as low as -30°C. “Again, to put that into context,
the average winter temperature in the Artic
is -34°C. With ultra-low maximum bowing
tolerances, limitations on door design are
removed. This includes the specification of dark
colours on south facing elevations.
This core stability also means that it achieves
high levels of weather performance and sealing,
offering a contemporary flush sash option across
21 styles, in addition to 30 insert panel options.
As a retail proposition, the Decalu88 bi-folding
door ticks a lot of boxes. ‘U’ Values are as
low as 0.68W/m2k triple-glazed or 1.4W/m2k
double-glazed. Sightlines are minimal, giving the
Decalu88 a contemporary premium aesthetic,
while there’s also a slim interlocking option.
With each sash able to accommodate weights
of 200kg and up to 3m in height, the Decalu88
bi-folding door, also offers impressive design
flexibility, while guaranteeing ultra-smooth
DECALU LIFT AND SLIDE
The Decalu163 lift-and-slide door is a heavyweight
contender. It accommodates individual
sash weights of up to 400kg on a single or
double track option.
That means it can be manufactured to achieve
an individual sash size of around 3,900mm by
3,500mm and comfortably manufacture to an
opening of up to 4,000mm tall by 3,500mm
long on a single run or 4m by 7m on a twin track
with just two sashes.
It’s available in a standard or slim interlock
option and in Deceuninck Aluminium’s standard
colour offer including dual-colour, textured and
marine grade finishes.
ENDING CALL BACKS FOR GASKETS
The use of co-extruded, pre-assembled gasket
across its door offer is indicative of the modular
approach adopted by Deceuninck Aluminium
across the system.
This immediately delivers major advantages to
fabricators in removing a process, contributing
to manufacturing efficiencies. “You don’t have
to have someone in the factory fitting gaskets.
They’re there already. It’s an instant saving on
time and labour costs,” adds Nigel.
This, he argues, extends to installers. “I’ve
installed the Decalu88 bi-fold and glazing is a
dream, the units just pop-in. The other major
advantage for installers is that because the
gaskets are co-extruded and backed with rigid
PVC-U, then pre-inserted they don’t shrink, so
you don’t get call backs.
“That’s such a big win. These doors do what
they’re meant to do. You aren’t fabricating or
fitting something that’s storing up problems
down the line. They are fit and forget products.”
